Abstract
Background and Aim: Despite its high prevalence, significant adverse consequences, considerable economic burden, and diverse clinical manifestations, insomnia remains a relatively under-recognized disorder. Accordingly, identifying contributing factors and developing effective therapeutic approaches is of undeniable importance. The present study aimed to investigate the effect of mindfulness-based cognitive therapy (MBCT) on cognitive emotion regulation and rumination in individuals with insomnia disorder.
Methods: This experimental study employed a pretest–posttest design with a control group and follow-up assessment. Using convenience sampling, 30 individuals with insomnia who sought treatment at clinics and counseling centers in Tehran were selected and randomly assigned to experimental and control groups. The experimental group underwent MBCT over a two-month period. Data were collected using the Cognitive Emotion Regulation Questionnaire (CERQ) and the Ruminative Responses Scale (RRS) before and after the intervention, as well as at a one-month follow-up. Data were analyzed using mixed-design analysis of variance (Mixed ANOVA).
Results: Findings indicated a significant effect of MBCT in reducing maladaptive cognitive emotion regulation strategies (F = 35.30, p < .001), enhancing adaptive cognitive emotion regulation strategies (F = 42.01, p < .001), and decreasing rumination (F = 170.34, p < .001) among individuals with insomnia. These improvements remained stable in both the posttest and follow-up stages.
Conclusion: The results demonstrated that MBCT significantly improved cognitive emotion regulation and reduced rumination. These findings highlight the value of MBCT as an effective non-pharmacological intervention for the management and treatment of insomnia.
